Crossota is a genus of hydrozoans of the family Rhopalonematidae. The genus comprises five species. Unlike most hydromedusae, these do not have a sessile stage. Rather, they spend their entire lives in the water column as plankton. The genus Crossota is widespread throughout the oceans.
Pleurothallis is a genus of orchids commonly called bonnet orchids. The genus name is derived from the Greek word pleurothallos, meaning "riblike branches". This refers to the rib-like stems of many species. The genus is often abbreviated as "Pths" in horticultural trade.
Cyrtodactylus is a diverse genus of Asian geckos, commonly known as bent-toed geckos, bow-fingered geckos, and forest geckos. The genus has at least 300 described species as of 2020, which makes it the largest of all gecko genera.
Rhopalosomatidae is a family of Hymenoptera containing about 68 extant species in four genera that are found worldwide. Three fossil genera are known.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
Pseudacanthicus is a genus of medium to large-sized suckermouth armored catfishes native to South America, where found in the Amazon and Orinoco basins, as well as rivers of the Guianas. They are primarily found in fast-flowing waters, sometimes relatively deep. They are sometimes kept in aquariums.
Crossota millsae is a species of deep-sea hydrozoan. These small ocean-dwelling creatures are bioluminescent; the light emitted by these jellyfish serves as a defense or warning to other creatures. Males and females have both been described, and it reproduces sexually. They are viviparous and females brood baby medusae attached to the gastric canals inside the sub-umbrellar space.
Crossota norvegica is a species of hydrozoan in the family Rhopalonematidae. It is closely related to Crossota millsae and is found in the Arctic Ocean at depths below 1,000 m (3,300 ft). Crossota norvegica is also known as the deep red jellyfish. This species is described as “alien-like” and is known for its vibrant red hue. It is a small cnidarian, reaching only up to 2 cm in its body size.
Rhopalonematidae is a family of hydrozoans. The family comprises 15 genera and 36 species.
Vampyrocrossota is a genus of hydrozoans of the family Rhopalonematidae. The genus only contains one species, Vampyrocrossota childressi. Unlike many hydromedusae, these animals do not have a sessile stage. Rather, they spend their entire lives in the water column as plankton. It is the only known species with a medusa that is truly black.
Benthocodon is a genus of hydrozoans of the family Rhopalonematidae. The genus contains two known species: Benthocodon hyalinus and Benthocodon pedunculatus, however due to the small size and red pigmentation, they can easily be confused with related genera. Unlike many hydromedusae, these jellyfish do not have a sessile stage. Rather, they spend their entire lives in the water column as plankton. The genus Benthocodon can be found near the sea floor in the Pacific Ocean from Antarctica to California to the Arctic Ocean.
Voragonema is a genus of hydrozoans belonging to the family Rhopalonematidae. The genus comprises four species. Unlike most hydromedusae, these do not have a sessile stage. Rather, they spend their entire lives in the water column as plankton. Centripetal expansions protruding from the ring canal is a characteristic that separates this genus from other genera in the family Rhopalonematidae.
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 630 species.
Pantachogon is a genus of hydrozoans of the family Rhopalonematidae. The genus includes three species.
Aglantha is a genus of deep-sea hydrozoans of the family Rhopalonematidae.
Aglaura is a monotypic genus of deep-sea hydrozoan in the family Rhopalonematidae. It is represented by the species Aglaura hemistoma.
Crossota alba is a species of hydrozoan in the family Rhopalonematidae. this species does not have sessile stage as other hydromedusae. Crossota is spread all over the ocean and lives their life in water as plankton. Crossota alba are commonly distributed in the west coast waters of India.
Stelis is a genus of kleptoparasitic bees in the family Megachilidae. There are at least 100 described species in Stelis.
Scelioninae is a subfamily of wasps in the family Platygastridae. It is a very large cosmopolitan group of exclusively parasitoid wasps, mostly small (0.5–10 mm), often black, often highly sculptured, usually with geniculate (elbowed) antennae that have a 9- or 10-segmented flagellum. It was formerly considered to be a family Scelionidae but has been reclassified as a subfamily of the Platygastridae.
Agathis is a genus of braconid parasitoid wasps. This genus was established by Latreille in 1804, and the type species is Agathis malvacearum Latreille, 1805. There are at least forty six species of Agathis in the western palearctic region.
